Based on the provided text from Chapter 39, what was Chand Patil's role and significance in Sai Baba's story?

Chapter 39 of the Shri Sai Satcharitra portrays Chand Patil as a meritorious man who played a pivotal, albeit unknowing, role in Sai Baba's story. He is credited as being the one who first "found this treasure" when he met Sai near a mango tree after losing his horse. The narrative states that it was because his nephew's wedding was arranged in Shirdi that the wedding party, which included Sai, traveled there. However, the chapter is quick to clarify that Chand Patil was merely an "instrument." His significance lies in being the vehicle for Sai's arrival in Shirdi, which was ultimately driven by Sai's own will to uplift his devotees.
